Prerequisites

Before integrating LicenseSeat into your application, make sure you have:

1. A LicenseSeat Account

An organization (created automatically on signup)
At least one Product configured in your dashboard
At least one License Plan for that product

2. Your API Key

Find your publishable API key in the LicenseSeat dashboard under Settings → API Keys.

Your key looks like pk_live_xxxxxxxx and is safe to embed in your apps — it can validate licenses and manage device activations, but can't perform privileged operations.

Tip: You have one publishable key per organization. It never changes and is always visible in your dashboard.

3. Understanding Your Integration Type

LicenseSeat supports two integration patterns:

Online Validation (Recommended)

Your app calls the LicenseSeat API to validate licenses in real-time.

Best for:

Desktop apps with internet access
Web applications
Mobile apps
Games with online features

Pros:

Real-time license status
Instant revocation
No cryptographic complexity

Offline Validation

Your app validates a signed license file locally, without internet.

Best for:

Air-gapped environments
Apps that must work offline
High-security deployments

Pros:

Works without internet
Tamper-proof via Ed25519 signatures
No server dependency at runtime

4. Technical Requirements

For Online Validation

Your app needs to make HTTPS requests. Any language or framework works:

JavaScript/TypeScript (Node.js, browser with proxy)
Swift (iOS, macOS)
C++ (Windows, Linux, macOS)
C# (.NET, Unity)
Python
Ruby
Go
Rust

For Offline Validation

You'll need an Ed25519 signature verification library:

Language	Library
JavaScript	`@noble/ed25519` or `tweetnacl`
Swift	`CryptoKit` (built-in)
C++	`libsodium` or `OpenSSL 1.1.1+`
C#	`NSec` or `Chaos.NaCl`
Python	`PyNaCl` or `cryptography`
Rust	`ed25519-dalek`
Go	`crypto/ed25519` (built-in)
